Specification of Letters Patent. i Patented lvlay 2, 1922,

Application filed June 10,1921. Serial No. 476,441.

ToaZZ whom it may concern:

ing devices adapted for use in shingling operations, and it consists in the combinations, constructions and arrangements herein de- In shingling a roof of a frame structure, the initial row or courseof shingles 1s arranged along one lower edge of the roof parallel with the ridge-piece of the latter and that the shingles of the next row or course overlie the upper portions of the shingles in the first course, as is well known. As is also well known, it is essential that the corresponding ends of the shingles of the second course and of each course thereafter be 'alined with one another and that lines tangent to the ends thereof shall be parallel with the ridge-piece of the roof.

It is therefore an object of my invention to' provide a device having means for detachably engagingshingles of a course to maintain the device in position to indicate shinglesof the next row or course. i

A further object of my invention is to provide a device of the character described having a body portion formed with one edge thereof a true straight edge and having means for detachably securing the body portion in adjusted position on a roof, whereby the shingles of a row or course will have their ends alined and be correctly positioned when arranged withtheir lower ends abutting the straight edge.

A further object of my invention is to provide a device of the character described that has means for indicating the portion of each shingle of a course that is to be covered by a shingle of the next course in order that the several courses or rows of shingles on a roof may be relatively arranged in accordance with a predetermined plan, such means being adjustable so that.

the extent of the portions to be covered may be varied as required.

A further object of my invention is to pro- Vide a device of the character described that relatively simple in construction and operatlon, easily applied andmanipulated,

and thoroughly practical commercially.

Other objects and advantages will appear in the following'specification, and the novel features of the invention will'be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing, forming part of this application, in which a I Figure '1 is a view, showing the device operatively applied,

F igure'Q is an enlarged plan view of the device,'and

- Figure 3 isfa section along the line 3-3 of Figure 2.

In carrying out my invention, I provide a body portion 1 which preferably is bar-like in form, as illustrated.

The body portion 1 is made of any suitable material, such as wood, that is sufliciently light in weight to afford ease of handling and at the same time strong enough to be durable in service. The body portion 1 is fashioned to provide a true straight edge '2. Extending transversely across the under face of the body portion 1 and at right angles to the straight edge 2 are parallel simi ar slots 3+3 arranged ad jac'enttoopposite ends of the body portion. Measuring bars l -4c are respectively slid ably. disposed in the guide slots 3-3. Each formed with a longitudinally extending slotb'fand'a retaining bolt 6 has its shank projected through the slot 5 andthrough an opening 7 through the body portion 1. A thumb nut 8 is screwed on the threaded end of the bolt 6 against awasher 9 that is disposed between it and the upper surface of the body portion so that each measuring bar 4 may be clamped to the body portion. in

adjusted position with respect to the latter when the thumb nut is tightened. The'head of the retaining bolt will then be flush with the lower surface of the body portion, as best seen in Fig. 3.

Each of the measuring bars 4:4: has marked on its upper face a scale indicated generally at 10 and having graduations rep-, resenting linear measurements. The measuring bars. 4-& are each formed with an integral attaching member at its end remote from the straight edge 2, each attaching member consisting of a portion 11 extending at right angles to the under surface of the bar 4 and an end portion 12 bent to extend in the same direction as the bar 4:

and parallel therewith. The under surfaces of the end portion 12 and of the bar 4 are v parallel with one another. .The end portion 12 is tapering in that the uppersurface thereof is slightly inclined from its extremv ity to' the point of its junction with the por- -.t-ion 11. The end portion 12 has its edges cut away at its extremity as indicated at 18 and 14:. The inner side of the portion 11 is parallel with the straight edge 2 and the scale 10 on the upper face of the bar 4 is arranged to indicate the distance between the inner side of the portion .11 and the remote end of the bar 1. The upper surface of the latter is likewise inclined from its extremity to a point intermediate its length, as best seen in Figure From' the foregoing description of the various parts of the device, the operation thereof. may be readily understoodf .After the first row or course of shingles 15, have been secured to the sheathing 16 of a roof 17 along a lower edge of the latter with the 7 upper ends ofthe shingles alined, the taperr 'ing portions 12 of the attaching members are inserted at the lower ends of certain shingles between such shingles andithe underlying sheathing until the innersides of the portions 11 abut the lower ends of the shingles. The thumb nuts 8 are then manipulated to permit adjustment of the body portion 1 with respect to the bars 4:4:. The body portion is secured in adjusted positionwhen the thumb nuts are tightened.

The, straight edge 2 will then mark the line of the lower ends of the next row or course of shingles, portions of which will be superposed on the shingles of the first row or course. A glance atthe scale 10 will reveal the length of theportion of theshingles of a the first course thatwill remain uncovered by the shingles of the second course since the straight edge 2 will be alined'with the graduation indicating the measurement of .that portion. Since each of the bars 4-4 is provided with a scale 10, the body portion the bar together;

1 can be readily arranged as required and the several courses of shingles may be spaced apart as desired.

It is obvious that a great saving in time and labor will result when my device is employed. Each shingle will be correctly positioned when placed with its lowerend abutting the straight edge 2 and consequently the care that has heretofore been necessary need not be exercised in, placing theshingles. The device can be instantly moved from one position to another since it is not secured to the roof'by nails or like fastening means, as is usual in similar devices of whic I am aware. V J

I claim:

l. A device of the character described comprising a body portion formed with a transversely extending slot in its lower face,

of the body portion at opposite sides of the latter, each of said bars being provided with an attaching member at its end remote from the straight edge, said attaching member consisting of a portion integral .withthe bar and extending at right angles thereto and a tapering end portion extending parallel with and in the same direction as the bar. and means for detachably securing the body portion to the bars.
